Construction Commences at New Sierra Pacific Power Plant
LCG, May 24, 2006--Sierra Pacific Power Company held the groundbreaking ceremony on Monday for its Tracy Combined Cycle Plant, which is scheduled to begin delivering electricity to the grid by June 2008. The new, gas-fired electric generating facility is located seventeen miles east of Reno, Nevada and is adjacent to the utility's Tracy Generating Station.
The Tracy Combined Cycle Plant has a design capacity of 514 MW and is estimated to cost $420 million. To minimize water consumption, the plant will be air cooled. Key contractors hired by Sierra Pacific Resources to build the project include: LG Constructors, a CH2M HILL subsidiary, for engineering procurement and construction services; General Electric, for combustion and steam turbine equipment; and Nooter/Eriksen, for the heat recovery steam generator.
The new plant will supply customers in Nevada and the Lake Tahoe area of California. According to Sierra Pacific Power Company, the new plant will increase the company's northern Nevada generating capacity by nearly 50 percent.
